Clear the Rails cache after modifying gitlab.yml

Defer LDAP defaults to upstream

Omnibus-gitlab should not have its own set of LDAP defaults. Either the
user adds a setting in /etc/gitlab/gitlab.rb, or gitlab-rails picks a
default value. Prior to this change, omnibus-gitlab would augment the
user settings in /etc/gitlab/gitlab.rb with its own set of defaults,
which is confusing and leads to configuration errors.

Changes in the dependency list trigger rebuilds of everything that comes
after. By moving gitlab-rails down, we make sure we do not have to
re-install the chef gem as often.

Omnibus-ruby 3.0 uses smart Git caching, removing the need to purge the
build. Also see:
